Answer:

2^-3

Step-by-step explanation:

Answer 2

Answer:

The answer is the second one: $(-1/2)^{-3}$

Step-by-step explanation:

1) When an exponent is negative, we must 'flip' the term before applying the exponent.

$(-1/2)^{-3}$ = $(-2/1)^3$= $-2^3$

2) Next, we need to cube two. Remember, the negative number does not apply yet!

$-2^3$ = -8

3) Thus, we get our answer. -8.
